flunc 0.8

Installation

We recommend installing into a Virtualenv.

You should be able to install flunc by using easy_install flunc; or you can download the tarball, extract, and run python setup.py develop.

Writing tests

Flunc tests are Twill scripts.

There is a firefox extension that allows you to record tests directly from within your browser. To install, visit

• http://sourceforge.net/projects/testgen4web/

These tests are saved in an xml format. You can convert these tests into a twill script by executing

testgentotwill recorded.html > twillscript.twill

Of course, you can still write tests manually.

Running tests

Run flunc --help for details on running the functional tests.

By default flunc will search ./ftests/ to find tests. You can change this with the -p (--path) option.

Some examples:

flunc all

runs all tests listed in all.tsuite against http://localhost/

flunc -t http://localhost:8080/some_portal all

runs all tests listed in all.tsuite against localhost:8080/some_portal

flunc -c all create_user

runs create_user.twill using all.conf

flunc -c all create_user login create_project destroy_project destroy_user

specify an ad hoc suite creating and tearing down a user and project on default host

Finding tests

Individual tests are contained in

<test>.twill

A suite of tests are contained in

<suite>.tsuite

Suite configurations are contained in

<suite>.conf

Cleanup suites are run after a suite, and are in

<suite>_cleanup.tsuite

More details are on the Flunc homepage.

0.8 (2011-04-04)

• Better behavior for the error case where search path (-p option) is nonexistent or not a directory (egj)

• Add optional second argument to url_qs command in flunc.urlinspector which, if present, asserts the value of the given querystring parameter, as well as asserting its presence. (egj)

• Add new command css_len in flunc.xpath which lets you test that a given CSS selector matches exactly N elements in the page (egj)

0.7 (2009-10-05)

• The -D (–define) command-line option now works as documented (egj)

0.6 (2009-07-06)

• Add extension module flunc.urlinspector with a command url_qs for making simple assertions about the current url’s query string (egj)

• Add notfind_in_css command to flunc.xpath (egj)

• Display a more meaningful error message for invalid argument-passing syntaxes (egj)

• Add a zope_cleanup.opencore_user_cleanup method to flush the opencore member cleanup queue when deleting users. No hard failure if you have a version of opencore that doesn’t support this (pw)

0.5 (2009-05-05)

• Add find_in_css command to flunc.xpath module. Use it to find a regex within a given CSS selector, like find_in_xpath (egj)

• Transfer binary data directly to the twill script for passed-in param values instead of escaping it as a string (cabraham)

0.4 (2008-12-18)

• Add two twill extensions to checkbox.py: not_selected, is_enabled (pw)

• Change is_selected to work correctly with checkboxes, I think (pw)

• Change default host to http://localhost (pw)

0.3 (2008-06-25)

• Add a twill extension (flunc.checkbox.is_selected) for making assertions about form defaults (pw)

0.2 (2008-04-14)

• Don’t display BadRequest exceptions when calling zope_delobject() – those are normal and just add a lot of noise (pw)

• Added twill extension to support xpath. This introduces a dependency on lxml. There is one function added: find_in_xpath (rmarianski)

  find_in_xpath runs a find command on the html result of an xpath expression For example: {{{ extend_with flunc.xpath find_in_xpath “People” “//div[@id=’oc-pageNav’]” }}}

• Altered the namespace behavior; now there is no leading dot to specify the global namespace. (jhammel)

  Instead, we use a scope-based model:

  1. items (tests, suites, configuration) is first looked up relavent to the current (local) namespace

  2. if they are not found locally, they are looked up in the global namespace

  The dot is still used for namespace separation. So looking up foo.bar will first look for the namespace foo in the local namespace; if this exists, it will try to look up bar in that. If foo is not a namespace relavent to the current one, it will try to look up foo.bar in the global namespace.

• Added hierarchal namespaces to tests (jhammel)

  Formerly, tests lived in a flat namespace. Using –recursive, one could put all tests under the root directory into a single namespace. Now each directory has a namespace associated with it. Tests or suites with single names refer to items in the same namespace (that is, the same directory). You may refer to the bar test or suite in the foo subdirectory as

  foo.bar

  If a suite has the same name as the subdirectory name, you may refer to it either with the full specification

  foo.foo

  or with shorthand

  foo

  To refer to the global namespace, preface the name of the test, suite, or path with a dot

  .foo.bar

  refers to the bar suite or test under the foo directory under the root directory.

  These changes should be backwards compatible with existing tests and were made to facilitate test organization with the hope of providing the flexibility to manipulate namespaces when tests live in multiple locations on disc.
